Yeah, for all she knows, he may very well have been a spy for the Kim regime, or there might be a hidden microphone present or something, and she and her whole family could end up sent to gulags for answering him.
I'm honestly struck by the sheer awfulness of Deslisle's tactics here. He put a woman and three generations of her entire family at risk just for his own personal greed.
Or she could have assumed, quite reasonably, that Deslisle was a dumb foreigner who could blurt out what she said to whatever person, out of ignorance.
There's another horrible bit near the end where Deslisle is on a tour where they describe alleged torturing of Koreans by US soldiers, and Deslisle thinks (sorry, the bad translation is mine) "our tourist guide was beautiful, and after hearing so many descriptions of torture, I began to imagine myself as a US soldier practicing new torture methods of my own invention on her".
I was speechless after reading that, my little remaining sympathy for Deslisle completely evaporating.
